Trait Implementations

impl<Key, Val> Clone for DefaultLifecycle<Key, Val>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Key, Val> Debug for DefaultLifecycle<Key, Val>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Key, Val> Default for DefaultLifecycle<Key, Val>

fn default() -> Self

Returns the “default value” for a type.

impl<Key, Val> Lifecycle<Key, Val> for DefaultLifecycle<Key, Val>

type RequestState = ()

fn begin_request(&self) -> Self::RequestState

Called before the insert request starts, e.g.: insert, replace.

fn on_evict(&self, _state: &mut Self::RequestState, _key: Key, _val: Val)

Called when an item is evicted.

fn is_pinned(&self, key: &Key, val: &Val) -> bool

Returns whether the item is pinned. Items that are pinned can’t be evicted. Note that a pinned item can still be replaced with get_mut, insert, replace and similar APIs.

fn before_evict(&self, state: &mut Self::RequestState, key: &Key, val: &mut Val)

Called when a cache item is about to be evicted. Note that value replacement (e.g. insertions for the same key) won’t call this method.

fn end_request(&self, state: Self::RequestState)

Called after a request finishes, e.g.: insert, replace.
